GUSTAV WEDEKIND, OF PHILADELPHIA, PENNSYLVANIA.-

INCOMBUSTIBLE-PAPER. SHADES FOR LAMPS.

Specification forming part of Letters Patent No. 38,523, dated May 12,1863.

.T 0 all whom it may concern.-

Be it known that I, GUSTAV WEDEKIND, of the city and county ofPhiladelphia, and State of Pennsylvania, have invented a new and usefulimprovement in the manufacture of incombustible-paper shades for lamps,gasburners, &c.; and I do hereby declare that the following is a full,clear, and exact description th ereot', reference being had to theaccompanying drawings, making a part ofthis specification, in whichFigure 1 represents a perspective view of the shade. Fig,2 represents asection through the same, to show how the picture, the mica, and theframe are united.

I am aware that a metallic frame with openings through it to expose thepicture, and a mica lining behind the paper picture to protect it fromthe heat of the lamp or gas burner, have been made the subject-matter ofa patent, of which patent, however, I am the assignee. In practice,however, I find several objections to this kind of paper shade, as thetin of which the frame was made must be painted, and the heat of thelamp or gas-jet would burn the tin and mar the paint. Besides, there was-too much shadow or opaque surface to the frame, and they were,moreover, heavy. These objections I have entirely obviated by myconstruction of the shade, andhave produced a paper shade which carriesits protector with it, and does not require either a separate protectoror chimney, as with the shades now in use that are made in whole or inpart of paper.

My invention consists in using ornamented or other suitable paper,backed by mica, and the two held together by delicate metallic rims attop and bottom, so that the whole surface of the shade may betransparent, and at the same time thevwhole surface be protected fromthe heat of the lamp or gas burner by the micabacking.

To enable others skilled in the art to make and use my invention, I willproceed to describe the same with reference to the drawings.

The paper a may be plain or ornamented, as may be preferred, and themica I) covers or backs its whole interior surface, and the two.

serve the paper or other equivalent substance while the whole surface isleft transparent or translucent, is the main purpose and object of myinvention and I thus produce a very handsome, light, cheap, and durablepaper shade.

The strips 0, instead of being folded to catch and hold the edges of thepaper and mica, may be otherwise fastened to and fasten said edges, butthe folding is found efficient and cheap. Soldering or riveting mightaccomplish the object, though not so-cheap as the folding.

Having thus fully described the nature and purpose of-my invention, whatI claim therein as new, and desire to secure by Letters Pa ent, is-

A paper shade, the whole interior surface of which is backed by mica,and the two layers ofpaper and mica are caught and held at the top andbottom thereof by a thin metallic strip or its equivalent, substantiallyas herein described and represented, and for the purpose described.
